error in spring 3 rest webservice 406 (Not Acceptable)

Question

My code:

<script type="text/javascript" src="JavaScript/jquery-1.9.1.js"></script>
<script type="text/javascript">
    $(document).ready(function() {
        $("#login").click(function() {
            var name1 = $("#eid").val();
            var pass1 = $("#p").val();
            var datacontent = {
                "empName": name1,
                "empPassword": pass1
            };

            alert(JSON.stringify(datacontent));

            $.ajax({
                type: "POST",
                accept: "application/json",
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                url: "/rest_test1/empLogin.htm",
                data: JSON.stringify(datacontent), // Note it is important

                success: function(data) {
                    alert(data.empName + " " + data.empPassword);
                }
                // error: function(data, status, er) {
                //     alert("Data: " + data + "Status: " + status + "Error:" + er);
                // }
            });
        });
    });
</script>

Controller code:

@Controller
public class EmployeeRestController {
    @RequestMapping(value = "/empLogin.htm", method = RequestMethod.POST)
    public @ResponseBody EmployeeVo doRegister(@RequestBody EmployeeVo employeeVo){
        System.out.println(employeeVo.getEmpName() + " " + employeeVo.getEmpPassword());
        return employeeVo;
    }
}

When I run this code values are shown in console but get error:

406 (Not Acceptable)

So below code is not working:

success: function(data) {
    alert(data.empName + " " + data.empPassword);
}

I used jackson-annotations-2.3.0.jar, jackson-core-2.3.4.jar, jackson-databind-2.3.4.jar Jar files.

HTTP status code 406 means the server cannot respond in the format mandated by the request's accept header. In other words, your web service isn't configured to generate an application/json response.

Try removing the accept: "application/json" from your AJAX request, or add the content type to your response, like so:

@RequestMapping(value="/empLogin.htm", headers="Content-Type=application/json", method=RequestMethod.POST)
